The formula for are of a circle is 3.14 X r squared.
Because radius (r) is half of diameter, you take 37.3 and divide it by 2 which is 18.65. Now you take 18.65 and multiply/square it by itself. 18.65 X 18.65= 347.8225. Now, you do 347.8225 and multiply it by pi or 3.14. 347.8225 X 3.14= 1,092.16265.
So your answer is 1,092.16265.
Hope this Helped!

When advertised the measure of a pizza is its diameter. A 24 inch pizza therefore should have a diameter of 24 inches.
If that is the diameter, divide by 2 to get the radius. Then use the formula: area = pi x radius2.
Is the 8 inches of the pizza the diameter or circumference? Is the 8-inches of the box the area of side length? If the diameter if the pizza and the side length of the box are both 8-inches, then the pizza will barely fit. If the circumference of the pizza is 8 inches, that means that the diameter is 8/pi = 2.546..... and that would fit in a box with side lengths of 8-inches. If the box's area is 8-inches, that means the side lengths are the square root of 8=2.828.... A pizza of diameter 8-inches won't fit, but a pizza of circumference of 8-inches will.
Area of pizza: 64pi square inches.

The 18" refers to the width (diameter) of the pizza.
The area of a pizza depends on the size of said pizza. If there is a certain pizza you would like to find the area of, all you need to do is: 1. measure the diameter of the pizza 2. split the diameter in half to get the radius 3. square the radius and multiply it by pi(3.14). For example, if I have a pizza with a diameter of 10 inches I would split that in half to get a radius of 5 inches. Then I would do this: (3.14) x 52. Which would end up being 78.5 in2. Tada, now you know how to get the formula of a pizza!
It is: 25*pi square inches

The answer is 6 inches.

10 inches, assuming the pizza box is square. If the area is 100 in2, then each side must be 10 inches long. Since the pizza goes from the end of the box to the other side, it is also 10 inches in diameter.
When advertised the measure of a pizza is its diameter. A 24 inch pizza therefore should have a diameter of 24 inches.
